The main purpose of the authority file of published patent documents is to allow all interested parties to assess the completeness of the available patent documentation from the industrial property office (IPO) that generated the authority file.
On this page, you can find the most recent authority files provided by the IPOs to the International Bureau of WIPO or links to the webpages where such authority files compliant with WIPO Standard ST.37 can be found. The recommendations on data elements, structure and format of authority files are provided in WIPO Standard ST.37.
The icons included within the table indicate the file type of the authority file and will initiate a download. The exception is 'HTML' which indicates that the Office is hosting the file locally and you will leave the WIPO website to go to the linked HTML page.
*The two links provided here are the same, as the definition file information is contained within the instance.
